-==== SPI updater image ==== +<note important>​Please unplug the power supply before proceeding to update SPI flash memory with update image in SD card. Otherwise, the update image would not be recognized and updating procedure would not start.</​note>​ 
-The **SPI updater image** ​is intended to update ​SPI memory ​with given firmware ​image and it is build to boot from SD card.+==== Recovery mode ==== 
 +The recovery mode is a useful method when Petitboot in SPI memory ​is corrupted or you are not sure what is in the SPI memory. This image is a complete firmware that can boot by itself and proceeding to flash SPI flash memory as soon as ODROID-N2 is booted.

-In order to flash the downloaded update ​image, you can use **dd**, **Echer** or any flashing tool for your convience.+The recovery ​image can be flashed with well-known flashing tools[[troubleshooting/​odroid_flashing_tools?​s[]=etcher#​using_etcher|Etcher]] and [[troubleshooting/​odroid_flashing_tools?​s[]=etcher#​using_dd_disk_destroyer|dd]].

-**SPI firmware image** is the image file in 8MB that is flashed into onboard ​SPI memory. ​This file can be recognized by U-boot of SPI memory and start to flash when the file is detected. The new SPI firmware ​image must be copied ​into the first partition ​of the SD card, not eMMC, eMMC may not help to update ​your SPI memory.+The **Upgrade mode** is to upgrade ​the contents ​in the SPI flash memory ​fully or partially whenever new Petitboot firmware is releasedCurrently, the SPI flash memory will be fully updated with the released firmware which size is 8MB. The upgrade ​firmware ​file must be copied ​in the file system ​of the first partition in micro SD card, not eMMC. Then U-boot will recoginize the firmware file and start to update SPI flash memory.
  
 In order to update SPI flash memory with this firmware image, for example, if you have an SD card with Ubuntu image from Hardkernel, then the name of the first partition is **BOOT**. In order to update SPI flash memory with this firmware image, for example, if you have an SD card with Ubuntu image from Hardkernel, then the name of the first partition is **BOOT**.
